The Minnesota Timberwolves are closing in on a deal that would swap forward Derrick Williams for Sacramento's Luc Mbah a Moute, according to sources with knowledge of the talks.

Sources told ESPN.com that the teams were progressing toward finalizing the trade Tuesday to give Williams the fresh start he's been seeking.

Williams and Mbah a Moute, sources said, have emerged as the principals in the latest talks between the teams, with offensively challenged Sacramento known to be pushing hard to be the club that lands Williams, who was selected No. 2 overall in the 2011 draft.
